Answer:
These all are constructors.
<u>CONS</u>
(CONS A B)
makes a pair like this: (A . B)
In other words, A is the CAR of the pair; B is the CDR of the pair.
For example:
(CONS 4 5) ==> (4 . 5)
(CONS 4 '(5 6)) ==> (4 5 6)
[The pair (4 . (5 6)) is the same thing as (4 5 6)].
<u>APPEND </u>
(APPEND A B)
makes a new list by replacing the final nil in A with the list B. A and
B must be proper lists.
For example:
(APPEND '(4) '(5 6)) ==> (4 5 6)
This takes any amount of number and put in this order
<u>LIST </u>
In this ,it will return a list whose elements are value of arguments in the order as it appeared in the LIST.It can take any amount of parameters
For example,
(LIST 4) ==> (4)
(LIST 4 5) ==> (4 5)
(LIST 4 5 '(6 7)) ==> (4 5 (6 7))
(LIST (+ 5 6)(* 5 6)) ==> (8 9)
The given question is not a true or false question. It is a Multiple Choice question. By googling it you can find the correct question here https://www.coursehero.com/file/poq0d6/The-practice-of-spamming-has-been-growing-because-a-it-is-unregulated-b-it-is/

Explanation:
Answer:
Following are the program in c++ language
#include <iostream> // header file
using namespace std;// namespace
int main() // main function
{
int num; // variable declaration
long int f=1; // variable declaration
do
{
cout<<"Enter the Positive value:";
cin>>num;
} while(num<0); // i check whether number is non negative or not
while(num>0) // iterating over the loop
{
f=f*num; // calculate the factorial
num--; // decrement the value of num by 1
}
cout<<" factorial is :"<<f; // display the factorial .
return 0;
}
Output:
Enter the Positive value:7
factorial is :5040
Explanation:
Following are the description of the program .
- Read the input by user in the "num" variable of "int" type..
- The do-while will check the enter number is nonnegative number.
- While(n>0) loop is calculating the factorial in the "f" variable .
- Finally display the factorial .
